Note 1ꢁ Absolute Maximum Ratings indicate limits beyond which damage to the device may occurꢁ DC and AC electrical specifications do not apply when operating
the device beyond its specified operating conditionsꢁ
Note 2ꢁ All voltages are with respect to groundꢁ
Note 3ꢁ Unless otherwise specifiedꢂ the Absolute Minimum Input Voltage is equal to the negative power supply voltageꢁ
Note 4ꢁ The maximum power dissipation must be derated at elevated temperatures as is dictated by T
